How to change the password in Android Safe?
There is no quick way to change the "system password" for Android Safe. Because there is none. Each note is encrypted individually. There is a workaround though. You may use the Export function to save your notes first. Then uninstall and re-install Android Safe with a new password set. Then import back the exported notes. But the import action will take some time as each note need to be decrypted and re-encrypted with the new password.
Since version 1.0.3, there is a menu option to change password.

Android Safe uses 256-bit AES encryption in ECB mode
Encryption keys are generated based on PKCS #5 (PBKDF2) with 1024 iterations
Each note is encrypted individually with a key generated by PBDF2 using a different 256-bit salt.
